Neotrypaea japonica (Ortmann 1891) is a burrowing shrimp that lives in tidal flats. In this study, 123 SNP markers were isolated and characterized from N. japonica. The frequency range of minor alleles varied from 0.2500 to 0.4833, the observed heterozygosity ranged from 0.4333 to 0.9000, and the expected heterozygosity ranged from 0.4944 to 0.6503. The polymorphic parameter and inbreeding value varied from 0.3680 to 0.5651 and − 0.2768 to 0.1045, respectively. Significant departures from Hardy–Weinberg equilibrium after Bonferroni correction (P < 0.05) were observed for 16 loci. The study of polymorphic SNPs will provide an important theoretical basis for further population genetic diversity analysis and species conservation of N. japonica.

Neotrypaea japonica (Ortmann 1891) 是一种生活在潮滩的穴居虾。在这项研究中，从粳稻中分离并表征了 123 个 SNP 标记。次要等位基因的频率范围为 0.2500 至 0.4833，观察杂合度为 0.4333 至 0.9000，预期杂合度为 0.4944 至 0.6503。多态性参数和近亲繁殖值分别在 0.3680 至 0.5651 和 - 0.2768 至 0.1045 之间变化。在 Bonferroni 校正后 ，观察到 16 个位点显着偏离 Hardy-Weinberg 平衡（P < 0.05）。多态性SNPs的研究将为进一步开展粳稻种群遗传多样性分析和物种保护提供重要的理论依据。
